Subject: Makefile: Distinguish DOC_OTHER from DOC_OUT.

DOC_OTHER includes dependencies that are neither scm files nor out
files, but are primary sources required for the build.

* Makefile.am (EXTRA_DIST): Add DOC_OTHER.
(doc/ccwl.info, doc/ccwl.html): Depend on DOC_OTHER.
* build-aux/find-dependencies.scm: Output DOC_OTHER.
(find-dependencies): Classify source forms as type 'out or type 'other
based on extension.
